' `This invention relates' to new and useful improvements in vaporizers, and 'particuf larly `to devices for" vapoi'izing liquid fuel.

OneA objectkof the vinventionv is to provide a device in which theliquid' fuel willfbe quickly vaporized and gasitied before being deliveredito thefburner. *'f

Another object is-to provide a simplev de vice Yof lthis character wherein the iow of vapor is readily .and properly regulatable.

Another'object is to provide a device of this characterwhich may bev easily and quickly taken apart for cleaning and adjuste ments. f Y

Other objects and advantages will be apparent fromthe following description when taken in connection with the accompanying drawing. l

In the drawing:

Figure 1 is an elevation of a burner equippedwith the present vaporizer, y

Figure 2 is a top plan view of the same.

Figure 3 is an enlarged vertical sectional view on the line 3-3 of Figure 2.

Referring particularly to the accompanying drawing, 10 represents a burner, which is mounted on oneend` of agas conduit 11,

and extending upwardly from said end of vthe conduit is an apertured` member 12. A

tee Coupling 13 isprovided with a` depend in-g `apertured lug 14 which receives a bolt 15 therethrough, said boltbeing also disposed through thel member 12, whereby to.k

secure the coupling 13 in proper position. Engaged on the other -end of the coupling is a cap y16, and formed on the intermediate vportion of the coupling, and depending therefrom, is a nipple 17, to which is adapted to be attached any suitable-conduit for con- ,veying liquid fuel thereto. Screwedinto the lug carrying end of the coupling 13 is one end of an oil vaporizing. and gasifying tube 18, and engaged ontheother end of the tube is a cap 19, the outer end of which is reduced, as shown at 20, and internally threaded to receive therein the hollow plug The cap `19 is formed witha chamber 22, between the reduced end thereof and the adjacent end of the tube 18. Disposed within the tube 18, and having a terminal flange 23 which is clamped between the. adjacent end of the tube and the cap 19, is a sleeve 211,r

said lsleeve being of an external diameter slightly less than-the interior diameter of' LIQUID-FUEL nonnen.

external diameter equalto thediameter of 'the sleeve 24, and held in 'spaced relation to the 4boieofthe coupling 13' by'the slightly smaller opening in the cap 16, through which said rod passes, The outer end of the rod is yprovided with hand wheel 26. The other end of the rod25 is reduced in diameter yand i externally lthreaded to be received in the sleeve-2l1l Beyond lthe threaded end of the rod there is a further reduction in the diameter of the rod, and screwed into the end of this further reduced portion of the rod is one end of a needlevalve 27, which is adapted to be moved longitudinally toward and a'wayfroin the opening in the cap `19, and into and out of saidy opening, whereby to regulate the flow of gas. The sleeve'24; is provided with longitudinal slots 28 whereby the gas, generated from the liquid fuel in the space between the tube 18 and the rod 25 may pass into the chamber@ The other end of the conduit 11 turns upwardly and inwardly toward the burner 10, and into this end of the conduit the cap 19 is disposed, for delivering gas to the conduit. The gas then passes through the horizontal portion of the conduit, and thence upwardly to the burner. By grasping the hand-wheel Aand turning the rod 25, said rod will, by

vtransversely of the burner 10, in position to be heated bythe Haine from the said burner, This heat from the burner will cause the liquid fuel, flowing from the tube 18, externally of the rod 25, to become vaporized and gasied, and flow into the chamber of the cap 19, by means of the slots 28, and thence out through the plug 21 to the conduit and the burner. Y

The vsmall space between the tube 18 and rod 25 permits the liquid fuel to spread out in a thin layer, so that vaporization will be more rapid, and as the burner 10 continues to heat the tube 18, the vapor will become gasified as it proceeds toward the outlet end of the vaporizer, and is constantly delivered to the burner 10. More gas will be gener ated than the burner 10 can burn, there! fore such excess gas will iow to the burners 30.

In opposite sides of the'horizontal portion of the conduit 11 there are formed the ,nipples 29 to which are adapted to be oonnected additional burners, which receive eX- cess gas generated in the tube 18. Each of the additional burners, which are shown at 30 is provided With a valve operable by the hand device 81.

That is claimed is:

In 'a burner for liquid fuel, a vaporizing and gasifying tube having a lateral liquid fuel inlet at one end and a gas outlet at the other end, an internally threaded and longitudinally slotted sleeve in the outlet end of the tube, a plug adjustable in said outlet'end and having a minute opening longitudinally therethrough, a rod longitudinally and centrally Within the said tube and spaced therefrom to provide a` narrow eiroumsoribing fuel vaporizing and gasifying passage between the inlet and outlet of the tube, one end of the rod being threaded into Said sleeve, a burner beneath the tube and being Connected with the gas outlet end thereof, a controlling needle valve on the sleeve engaging end of the rod movable in said minute opening, and means for rotating the rod to thread the same through the sleeve and move the needle into and out of the minute opening and cover and uncover said slots.

In testimony whereof, I aflix my signature. a
